XP95 I.S. Optical Smoke Detector

Product code: 55000-640APO

55000-640APO - XP95 I.S. Optical Smoke Detector
Optical smoke detectors incorporate a pulsing LED located in a labyrinth within the housing of the detector. The labyrinth is designed to exclude light from any external source. At an angle to the LED is a photo-diode which, in clear air conditions, does not receive light directly from the LED. The detector transmits a clear air signal to the control panel. When smoke enters the labyrinth, light is scattered onto the photo-diode and the signal to the panel increases. The signal is processed by the electronic circuitry and transmitted to the control equipment in exactly the same way as in the case of the ionization smoke detector. Full details of the principles of operation and the electrical description are published in the XP95 Engineering Product Guide. XP95 I.S. detectors have the same operating characteristics as the standard versions.

Brand Information

XP95 Intrinsically Safe (IS) detectors are a development of the well established analogue addressable XP95 range from Apollo. XP95 IS detectors feature all the benefits of the standard range, but are developed specifically for use in hazardous areas. The addresses of XP95 IS detectors are set by means of the patented XPERT card.

Additional Information

Operating temperatures (ambient): –20°C to +40°C (T5) –20°C to +60°C (T4)
